Problems solved by technology

[0004] Therefore, before irradiation processing, it is necessary to know the dose distribution data of the goods. At present, the commonly used detection method is to check the goods out of the box and embed the dosimeter in the test object for testing, which has low efficiency, high cost and high technical requirements.

Abstract

The invention discloses an article space dose distribution detection method and device. The article space dose distribution detection method comprises the steps that a dose distribution standard modelis constructed, wherein the dose distribution standard model comprises a standard mapping relation between dose distribution data and density values of an article under irradiation of energy of a preset size; perspective scanning is performed on the article to be detected, and a three-dimensional perspective image of the article to be detected and detection density values of all space points of the article to be detected are obtained; the dose distribution data of all the space points of the article to be detected are obtained according to the detection density values of all the space pointsof the article to be detected and the standard mapping relation of the dose distribution standard model; and the dose distribution data of all the space points of the article to be detected are matched with the three-dimensional perspective image and displayed. According to the article space dose distribution detection method and device, the dose distribution data of all the three-dimensional space points of the article to be detected are more visual and accurate, and reasonable configuration of various parameters in the irradiation process is facilitated.

Description

technical field [0001] The present disclosure relates to the field of radiation processing, in particular to a method and device for detecting the spatial dose distribution of an item. Background technique [0002] Irradiation processing is to use the physical, chemical and biological effects of radiation on substances to achieve the predetermined target effect. It can be used for food preservation, disinfection and sterilization of medical and health care products, disinfection and sterilization of packaging materials, cosmetics sterilization, and material modification. Irradiation processing involves a wide range of fields. It is an important processing link in industries related to the national economy and people's livelihood, such as food processing and medical and pharmaceutical processing, and has become an important component of the national economy. [0003] When electron beams are used for irradiation processing, due to the limited penetration of electron beams, th...
